I mean.. tech people are kind of nuts on this.

For literally years Google Authenticator had no means to move between phones. Of course people who were told to use it decided never to use OTP apps again after getting screwed.

Yubikeys (and google's keys) have had issues where the keys were extractable and needed to be replaced.

and so on.

SMS has just worked. Yes, it has reliability issues, but it's almost like people can't model even the most basic ways that the non-SMS tech is basically terrible. Even Apple doesn't work well because of the broadcast behavior of the confirmations.
